My invention relates to tie plates lor use in locations Where frog or cross-over structure or the nearness of rails in railv structure prevents the placing of separate tie plates of.A the usual type. l

A purpose of my invention is to provide tie plates adapted. to give adequate support throughout the Width of a frog or cross-over, or across beneath both rails of rail structure Whose proximity prevents the use of separate plates.

A further purpose is to provide tie plates of the seme length for Widely varient Widths et dierent portions of the length of the structure; such as, for instance, between the parts' of a :frog of different Width.;

A. further purpose is to piece two tie plates side by side on thesame tie, each tie plete being edaptedto give lull width support beneeth s Wide frog or rail structure end each tie plate being adapted to hook over or -orm en abutment for one side-of e frog or 'rail flange which rests ion the two pletes,vhoolring the respective plates over opposite bottom joint plates Where these occur.

A. further purpose is te retain u, fro or crossing aga-inst lateral movement end ulljr und fairly supportit ecross its entire fece et minimum cost and Without restreint against vertical movement.

l have elected to illustrated one general form only of my invention, with slight modilieetifms9 selecting a. form that is practiced and eicient in operation and 'which Well illusu Figure'l is a. fragmentary top plan view illustrating e. frog supported by tie plates embodying e desirable form of my invention.

Like numerals refer to like parts in all figures.

llescribinglin illustration endI not in limitation and referring to the drawings In usuel, railroad practice frogs and cross overs have required special tie plates in order that they muy be properly supported und that ree in width with the variant q the tie plates@J l regs et the points Where the widths 'of the ties are located, Av similar situation has arisen 'at the heel ends of switches where the rails have separated, but have not seperated far enough to permit the placing of seperate tie plates of the normal type.

.ln all such locations Where there is not room for separate insertion of individual tie plates, the number of diferent special tie Blutes required has been increased not only y the need of support at different Widths of frog or rail spacing9 but by the further fact thetthe placin of the ties is not ys'i'iciently uniform and t e variation of" the frog (or crossing)v width and taper is so greet that special tie plates have been required to lite greatmeny otherwise unnecessary slight va.i riatio'ns in frog Widthn Each tie plete has occupied thel entire width of the tie and in order to support against movements in both lateral. directions by the same tie plate, the ebutments for both sides of the frog or crossn in have been carried' upon the same plate.

ot only hss this required e very considerq able number of different sizes of tie plates,

but the vselection end placing of them has required an undue amount of installation time and cere I rovide cooperating tie plates, preferably; ut not necessarilyl used, two at each tie, adapted tobe used 'with equal ease and eiiectivene at the successive ties along the length 4 of e frog or crossing, whatever its Width.

My cooperating tie 'og or crossing, lirrnly fasten both sides oit 'the frog or crossing to the il tie, present lateral abutments to both sides of the rail, firmly supporting the rail from movement in either direction along the tie and extend beyond the points of engagement;`

V with the frog or crossing to prevent tiltingof the structure to the injury ot' the ties.

In Figures l and 2 I have shown a conventional `form of frog made up from rails, filler members and a casting but without any thought ol restricting it to a frog of this character as distinguished from a frog made up only of rails and filler members or made up of cast parts in Whole. or in part, and with knowledge'that my invention .is applicable not only to composite or separat-ely cast frogs but composite or separately cast crossings or for the support of diverging rails whose spacing or other setting makes it desirable Lto use tie plates common to both rails.

The application to the rails'is also obvious-v4 ly independent of whether the rails be parallel or be spreading as at the heel of a switch.

As will be seen in the illus/tration, the rails l0 and ll approach each other to a point 12 Where a filler member is inserted forming part of the frog. The frog tapers outwardly from 13 to le, is approximately straight to a point 15 and then tapers outwardly to 16. The right end of the frog terminates in di verging,r rails 17 and 18; v

My tie plates are applicable to the entire frog length and to a suliicient distance 'from the'ifrog 'for the rails to have diverged to permit separate tie plates lto be 'placed beneath them upon the same tie The cross section shown in Figure 3 is a conventional one and is shown for the purpose of completeness only and not with' any thought ot restricting to the particular arrangement ot' rails and lillernieinbers from which the frog is made up at this point.

I place two cooperating' duplicate tie plates 19 and 20 under the rail side by side upon each tie 2l, the pair of plates desir-ably having a combined width about equal to that of the tie.

Each plate is provided with. a fiat upper surta ce'22 giving adequate rm support to the frog and an upwardly directed hook 239 2, or 232 near one end directed inwardly and adapted to hook over one 'flange of the frog, crossing or rail or form an abutment against a splice bar there bc a joint at this location.

The extensions 2e and 25 beyond the frog support against tilting strains.

l' also provide each plate with periorations v 525 naar nach end for spikes 27 used in spill:-

ing the plate to the tie.

The tie plates are fastened. side by side on the tie with the hochsengaging the opposite flanges, so that the plates are in dierent relamesses tive longitudinal positions according to variation in the width between 'the opposite anges.

Thus at a narrow portion of the structure, each plate has considerable extension at 28 beyond the hook end of the other plate, While, Where the structure is of considerable Width, each plate may have but little extension beyond the other plate, reaching 'far enough however, for easy access to the perforations 'for spiking the plate to the rail and to sup,- port against tilting.

Though the hook support for the flange of a frog or crossing may be quite desirable in sonic locations as preventing the frog or crossing from riding high enough so as not to come down in the same 'tie plate location, l have discovered 'that` it has the disadvantage ot tending` to litt the tie plat-e and hence thev tie with the frog or crossing;- due to 'the vvave motion of the entire track with passage ot heavy tradic.

l secure the advantage of labutment to pren vent side movement and at the same time ,avoid the possibility of the frog or crossing failing to register with the plate in the same position as before by using a stop 23 shown in Figure 8 which is deliberately made. high enough to avoid all possibility of the frog or crossing climbing this abutment. Theoretically the space under the hook could be made high enough so as not to interfere with vertical movement, but this oifers serious =objection of' extending the end of the hook in Wardly to a plate Where it may interfere with bolts placed through thestruc'tnre Whether, frog crossing;1 orlsvvitch heel, giving a maf' terial advantage to the stop form shown in Figure 8.

My invention is applicable in its broader aspects to any iorm oi" abutment.. Whether it be integral, punched up, as in Figure 5, or riveted as in Figure 67 or 'Welded as in Figure lit is not my intention to claim specifically the Welded form Which'is included because it comes Within. the broader `features of nay invention.

in previous attempts to use tie plates provided With a single hook 'for each flange, no one has recognized that 'the extension o these plates to 'form adequate support 'forthe full Width oit a -frog or crossingr would Ineke them applicable to such use and l believe that l ain the first to provide a tie plate containing character of abutment for one side of a frog or crossing and long enough to be applicable throughout structures of this character and that l am 'the irst further to provide 'for adequate support of any such tie plate beyond the point of engagement of the hook with the structure.

i believe myself to be the rst also to pro vide an abutment :tor a tie plate adapted ttor such use which tree from inward exten .ico

sion above the flange and yet is highenough to prevent climbing of the abutment.

In referring to frogs and cross-oversk I have intended to cover the whole grou of structures in which fro'gs`occur, inclu ing not only the technical structure but also the vuse'of the frog in crossings,crossovers, turnouts and all other structures where the condition of variant width o base of the structure to be supported by the tie plate is foundl In view of my invention and disclosure variations and modifications to meet individ- '.ual whim or particular need will doubtless become evidentto others skilled in the art,.

, and having perforations near opposite-ends to obtain all or part of the benefits` of my invention Ywithout copying the structure shown, andv I, therefore, claim all such in so far as lthey fallwithin the reasonable spirit and scope of my invention.

, Having thus described my invention, what I claim as new and desire to secure by Letters Patent is ty l 1. A plurality of ties, a frog or cross-over having ianges'at opposite sides and aplurality of tie plates therefor having the same tie plate length for the different widths of the frog or crosssover and arranged in pairs, one tie plate of each pair having an upwardly and inwardly directed hook engaging one side of the frog or cross-over, extending well beyond the frog or cross-over at both ends for fasteningthe late to the tie, and the other tie plate of t e pair like the frstbut turned end for end with respect to thev `irst and having its hook engaging the o posite side of the frog or cross-over fromt at enp gaged by the hook of the first plate.

2. .A frog'or cross-over and a pluralityqof tie plates arranged in vairs, having the same tie plate length for t e different widths of the frog or cross-over, each plate of each air extending completely across beneath the rog or cross-over and apertured for fastening to'- atie at each end in the extension beyond the frog or cross-over and adjoining plates having abutments on opposite sides of the frog or cross-over to'engage with it and maintain its lateral osition, the abutments being substantially ree from lateral extensions and hi h enbugh to avoid dangerv of climbin by t e frog or cross-over.,

3. A rog or cross-over and a plurality of tie plates' therefor having the same 'tie plate length for the diii'erent widths of the frog or crossover and arranged in pairs, the tie plates of each pair supporting the frog or crosseover throughout its entire width and being provided with abutments engaging the ed es of the frog or ycross-over on opposite si es, one abutment on each tie late.'
